    My PowerBook G4 (1.25gHz 2003-4) has developed a problem all of sudden with the screen. Please see picture.

    If you're not sure what you are looking at, there are a series of horizontal & vertical lines/patterns in various colours. They are all uniform and not random.

    The PB starts up OK and you can probably see my desktop image (David Hockney painting) below all the interference.

    I have since run first aid - done a complete clean install and put a new system on there, but with no luck.

    I'd like to get it fixed so that my two girls can use it instead of my new MacBook Pro.

    Any suggestions please? Thank in anticipation of your replies.

    Most likely a hardware issue.

    The video cable that is routed through the hinges to the LCD screen might have been damaged causing the garbled video.

    Also a possibility is the video board is damaged.

    Both would probably be cost prohibitive to fix.

    If it's the video cable, some people have been able just to replace that. However, getting to the cable is going to be messy.

    If it's the video board, you would need a new one. It would be (slightly) easier to put in, however, would be more expensive to purchase.

    A used Powerbook in good shape would only be a few hundred dollars.
